The choice gives the Blackphone plenty of performance, making it an attractive device beyond the privacy-conscious consumer or business user.

Beneath the hood

Other specs for the Blackphone include a 4.7-inch IPS high-definition display with four point multi-touch, 1 GB of RAM, 16GB of onboard storage, an 8 megapixel rear-facing camera, a 5 megapixel front-facing camera, and Android 4.4, better known as KitKat.

"With Blackphone we have engineered a high-end smartphone rivaling the top devices on the market in terms of performance and user experience – and with comprehensive embedded privacy features as a crucial differentiator," said Toby Weir-Jones, CEO of SGP Technologies.

"Nvidia's industry leadership and the compelling advantages of their Tegra 4i mobile processor make them a key partner in creating a disruptive product backed by the best components available."

Pre-orders for the Blackphone opened in February. The phone launches in the US and EU in June.
